Simultaneously with the raising ofthe valve the enlargement 10 on the valve-stem forces the catch device 16 to the left, Figs. 1 and 4, until such enlargement passes beyond the eXtreme end 18 of such catch, whereupon such end will engage underneath the shoulder 11, whereby the valve will be held in its elevated position' although the pressure on the push-button and levers has been withdrawn. The catch 'will hold the valve in this raised position until the level ofthe water in the tank has been lowered substantially to the plane of the valve, whereupon the ball-float 15 will move downward with the receding Water, throwing the catch 16 to the left, Figs. 1 and 4, and releasing such catch from its engagement with the valve 4. The valve will now drop by gravity upon its seat, and the tank will again become filled with water, owing to the opening of the ball-cock 30. When the tank is illed with water, the float 15 is submerged, and its tendency is to rise to the level of the water, but is stopped by contact of its stem 14 against the top side of the opening 33 in one of the standards 5, through which it passes. When the valve is raised, as hereinbefore set forth, the enlargement 10 acts in the manner of a wedge against the point or hook-shaped end 18 of the catch device, which consequently bears against such enlargement after it has been slightly raised from its seat, so that such end or hook is ready vto engage at the very instant the shoulder 11 rises above its plane. It will be observed that the engagement of the catch and valve-stem is accomplished by means of a very short range of movement of the catch device, which is pivoted and arranged as close as practical to the central axis of thel valve and its stem, and it is due to this fact, among others, that a positive and effectual engagement ofthe valve is obtained at every operation.

While the above-described construction is the preferable one, yet it is to be understood that I do not intend to limit myself to the details in construction, but that various mechanical changes might be made therein without departing from the spirit of my invention.

I claim- 1. A discharge device for cisterns and the like comprising a valve having a stem and governing the discharge-passage and means for holding the valve open, when opened until the water is drained from the cistern and consisting of a catch device having a ring or curved member extending on either side of the valveestem with a ball-float rigidly connected thereto at one end whereby such ring 'moves with every movement of the iloat and a hook o1' catch proper at the other end to engage the valve when raised, said l'loat actuating the catch to both engagement and disengagement position and transmitting all its movements to such catch.

2. In a cistern for water-closet valves and the like the combination of avvalve having a stem and governing the discharge and a catch device comprising a curved or ring portion 12 surrounding the valveestem and a hook 16 on the ring and pivoted at its upper end and also having a curved end 18 adapted to engage the valve when raised and a float connected to said ring at a point substantially opposite the hook 16.

3. In a cistern for water-closets and the like, the combination of the nozzle or outlelpipe leading from the cistern and having a valve-seat, a valve seating on said seat, and having a stem, an upwardly-extending frame in said nozzle, a cross-bar on such frame, and having a central hole to receive and guide said lstem and also having a slot at one side of said hole, lugs on the cross-bar adjacent to said slot and a lioatactuated catch passing through said slot and pivoted to said lug, said catch having a hook adapted to engage the valve when raised.

4. In a cistern and the like, the combination of a nozzle 2 having a seat 3, a valve 4 seating thereon, a valve-stem 9 having a truncated conical projection 10, standards 5 on the nozzle, a cross-bar 6 between. the standards and a catch device comprising a ring-piece 12 having on one side a hook proper 16 with pivotal connection at its upper end on the cross-bar at 17 and having a curved depending end 18 adapted to engage under said projection 10 when the valve is raised, a iioat 15 and a stem 14 connecting the iioat and ring.
